Function try_with_timeout 

pub async fn try_with_timeout<T, E, Fut>(
    duration: Duration,
    future: Fut,
) -> TimeoutResult<T, E>
where
    Fut: Future<Output = Result<T, E>>,

Executes an async operation with a timeout, returning a TimeoutResult.

Unlike panic-on-timeout helpers, this function doesn’t panic on timeout but returns a structured result that the caller can handle.

Example

use error_rail::async_ext::try_with_timeout;
use std::time::Duration;

match try_with_timeout(Duration::from_secs(5), fetch_data()).await {
    TimeoutResult::Ok(data) => println!("Got data: {:?}", data),
    TimeoutResult::Err(e) => println!("Error: {}", e.error_chain()),
    TimeoutResult::Timeout(d) => println!("Timed out after {:?}", d),
}
